M83723, EN2997 & ESC10 Connectors
M83723, EN2997 & ESC10
Connectors
A family of miniature circular connectors based on the MIL-DTL-83723 (m83723) form factor.
These are for use in demanding applications such as military and commercial aviation engine sensors.
The following variants are available:
MIL-DTL-M83723
US Specification for 200°C, firewall, high vibration, medium density, threaded coupling connectors for aerospace applications;
EN2997
European Specification for enhanced performance, high temperature (260°C), firewall, enhanced high vibration, threaded coupling, engine connectors used by European customers derived from MIL-DTL-M83723;
ESC10
Rolls-Royce Specification for enhanced performance, stainless steel, high temperature (260°C), firewall, enhanced high vibration, threaded coupling, engine connectors derived from MIL-DTL-M83723;
BACC63CM/CN
Boeing Specification for enhanced performance, stainless steel, high temperature (260°C), firewall, enhanced high vibration, threaded coupling, engine connectors derived from MIL-DTL-M83723 & ESC10.
OVERVIEWS
M83723 Overview
- Description: miniature circular connectors meeting the MIL-DTL-83723 specification;
- Coupling:
- Bayonet option – quick and positive 3 point mechanism with visual confirmation of complete coupling;
- Threaded option – with visual confirmation of full coupling.
- Temperature range: –65°C (–85°F) to 200°C (392°F)
EN2997 and ESC10 Overview
- Description: improved miniature circular connectors based on the MIL-DTL-83723 form factor;
- Coupling: screw coupling with additional anti vibration features
- EMI Shielding: to 100 MHz at 1 GHz attenuation > 65 dB due to improved bottoming;
- Mating: Interchangeable and intermateable with MIL-C-83723 Series III type (note that when EN2997 or ESC10 specified connectors and mated with MIL-C-83723 Series the performance specification will meet the lower performance of MIL-C-83723).
M83723 connectors
M83723 Products Options:
- Coupling styles: Bayonet or Threaded Plugs and Receptacles (both coupling styles inter-mate with MIL-DTL-26500 connectors, except shell size 8 threaded);
- Contacts: Rear mounted inserted and removable using standard qualified plastic tools thus avoiding potential damage to the front sealing face;
- Body Materials: Aluminium and Passivated stainless steel versions;
- Mounting: A variety of mounting configurations including wall mount, nut, straight with RFI grounding;
- Finishes:
- Electroless nickel;
- Olive drab cadmium;
- Black anodizing.
- Commercial equivalents;
- Alternate key/keyway positions prevent cross mating of adjacent connectors having the same insert arrangement;
- Positive alignment of pin contacts by the lead in chamfers of the closed entry hard socket inserts;
- Raised moisture seal barriers around each pin contact that mates with the lead in chamfers of the hard socket insert;
- The elastomer grommet is able to seal over a wide range of wire diameters and has a triple wire seal in each cavity;
- The rear release crimped contact system features a stamped retaining clip captivated by moulded in shoulders of each contact cavity in the insulator. This produces a very stable contact;
- High-temperature firewall versions.
EN2997 and ESC10 connectors
An enhanced version of the MIL-DTL-83723 connector, these connectors feature improved anti-rotation on the thread coupling and will accommodate both the older generation and the latest generation of wire sizes.
